The planets Mercury and Venus has the closest average temperature
What are Planets?A planet is an astronomical object that orbits a star or stellar remnant that is large enough to be rounded by gravity, but not so large as to trigger thermonuclear fusion, and that is free of planetesimals in its locality
Planets are generally divided into two main types: large, low-density gas giants and smaller, rocky terrestrials.
In order of increasing distance from the Sun, they are the four terrestrials, Mercury, Venus, Earth, and Mars, then the four gas giants, Jupiter, Saturn, Uranus, and Neptune
Given data ,
Let the first planet be represented as A
Let the second planet be represented as B
Now , the planets A and B have similar average temperature
where , the planets can have negative as well has very high temperatures
Now , when A = Mercury and B = Venus
Venus has 864 degrees Fahrenheit (462 degrees Celsius)
And , Mercury has 800 degrees Fahrenheit (430 degrees Celsius)
So , both Venus and Mercury has similar temperatures
Now , when A = Neptune and B = Uranus
Neptune has minus 353 degrees Fahrenheit (minus 214 degrees Celsius)
Uranus has minus 374 degrees Fahrenheit (minus 224 degrees Celsius)
So , both Neptune and Uranus has similar temperatures
Hence , the planets are Venus and Mercury

HELP!!! I MIGHT FAIL THE 6th GRADE IF I DON'T GET HELP!!!! The southern United States experiences periodic occurrences of severe cold and drought conditions. Which weather phenomenon most likely causes this and why?
Answer:
La Niña, because the jet stream is displaced northwards
Explanation:
La Nina is known to be a cool phase that affects the average ocean temperature. During this period the surface wind becomes stronger and there is lesser rainfall over the areas of the central tropical Pacific to which the Southern United States belongs.
Hence, when the southern United States experiences periodic occurrences of severe cold and drought conditions, the weather phenomenon most likely causes this and why is "La Niña, because the jet stream is displaced northwards."
If a spring has an elastic potential energy of 60 J and a displacement of 4 m , what is the spring constant of the spring?
Answer:
7.5 N/m
Explanation:
Potential energy of a spring can be calculated using below formula
Potential energy= 1/2kx^2
potential energy = 60 J
X= displacement = 4 m
K= spring constant=?
Substitute the values we have
60= 1/2 × K × 4^2
60= 1/2 × K × 16
60= K × 8
K= 7.5 N/m
Hence, the spring constant of the spring is 7.5 N/m

calculate the kinetic energy of car of mass 150kg moving with velocity of 30km/h. what will be the kinetic energy when it's velocity is doubled and then tripled?
Answer:
The correct answer is -
1. 67500 J
Explanation:
The formula for KE is
K. E. = 1/ 2 *m v ^2
So input the values we know:
K . E. = 1/2 ⋅*150 *30 ^2
K . E. = 150 * 900 /2
K . E . = 67500
K . E. = 67500
If the velocity is double then;
use 2v in the formula
K. E. = ( 1/ 2 )*m(2 v) ^2
= (1/2)*4m v ^2
it is four times to original Kinetic energy, and similarly if tripled then, it will be 9 times to original.

(0) what is meant by regeneration,
(ii) why an analogue signal cannot be regenerated
Explanation:
1.) Regeneration is the natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body parts to full function in plants and animals.2.) When noise is added to analogue signals, it usually sounds like background hiss. Such noise can not be removed so the original clean signal can not be re-created or re-generated.
Which TWO statements explain how water changes when its temperature decreases from 70 degrees to 28 degrees?
explain a conventional method of heat transfer.
Conventional method of heat transfer.
Convection refers to a method of heat transfer where food is heated by a moving heat source such as hot air inside an oven that is circulated by a fan.How it works?
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. As a result, the particles take up more volume.For example:
Conventional ovens, which do not have fans, rely primarily on radiation from the oven walls, and to a lesser extent, on natural convection caused by temperature differences. The fans in convection ovens allow more heat to be transferred via convective heat transfer.Learn more:

Elsa runs 100m. She takes 20s to run this distance. What is Elsa's average speed?
Answer:
Average speed = 5 m/s
Explanation:
Given the following data;
Distance = 100m
Time = 20 secs
To find the average speed;
Speed = distance/time
Substituting into the formula, we have;
Speed = 100/20
Speed = 5m/s
Therefore, Elsa's average speed is 5 meters per seconds.

What is the Coriolis effect?The Coriolis Effect can be described as an apparent effect generated by a rotating frame of reference. The effect takes place when an object moving along a straight path can be viewed from a non-fixed frame of reference.
The moving frame of reference is the one in which the Earth rotates at a fixed speed. The Coriolis effect creates wind patterns near the earth’s surface, that move to the east toward the equator and to the west toward the poles. These wind patterns are responsible for moving clouds around the globe and creating weather patterns.
Coriolis force can be described as a fictitious force resulting from the rotational movement of the earth. It only affects the wind direction and not the wind speed. The magnitude of Coriolis force can be calculated from the wind speed.

Frank has a mass of 30 kg. He is sitting on a swing which is 2.3 m long. His dad pulls him up to a height of 1.2 m above his lowest point and releases him.
b. What is his velocity at the bottom of his path?
Answer:
His velocity at the bottom of his path is approximately 4.85 m/s
Explanation:
From the question, we have;
The mass of Frank, m = 30 kg
The length of the swing which he is sitting on, l = 2.3 m
The height above the lowest point to which the dad pulls him, h = 1.2 m
Potential energy, P.E. = m·g·h
Where;
g = The acceleration due to gravity ≈ 9.8 m/s²
The maximum potential energy Frank gains, P.E.[tex]_{max}[/tex] is goven as follows;
P.E.[tex]_{max}[/tex] = 30 kg × 9.81 m/s² × 1.2 m = 353.16 J
Therefore, by the principle of conservation of energy, we have;
The maximum kinetic energy at the bottom of the swing, K.E.[tex]_{max}[/tex] = P.E.[tex]_{max}[/tex] = 353.16 J
K.E. = 1/2·m·v²
Where;
v = The velocity at the bottom of his path
∴ K.E. = 1/2 × 30 kg × v² = 353.16 J
v² = 353.16 J/(1/2 × 30 kg)
v² = 23.544 m²/s²
v = √(23.544 m²/s²) ≈ 4.85 m/s
His velocity at the bottom of his path, v ≈ 4.85 m/s
If a car accelerates from rest at a constant 4 m/s
, how long will it take for the car to reach a
velocity of 28 m/s?
Answer:
The time it will take for the car to reach a velocity of 28 m/s is 7 seconds
Explanation:
The parameters of the car are;
The acceleration of the car, a = 4 m/s²
The final velocity of the car, v = 28 m/s
The initial velocity of the car, u = 0 m/s (The car starts from rest)
The kinematic equation that can be used for finding (the time) how long it will take for the car to reach a velocity of 28 m/s is given as follows;
v = u + a·t
Where;
v = The final velocity of the car, v = 28 m/s
u = The initial velocity of the car = 0 m/s
a = The acceleration of the car = 4 m/s²
t = =The time it will take for the car to reach a velocity of 28 m/s
Therefore, we get;
t = (v - u)/a
t = (28 m/s - 0 m/s)/(4 m/s²) = 7 s
The time it will take for the car to reach a velocity of 28 m/s, t = 7 seconds.

If an owl produces two pellets every 24 hours and each pellet contains the remains of 3 prey, how much does it eat in a week? A month?
The owl eats 42 prey in a week and 180 prey in a month.
To calculate how much the owl eats in a week and a month, we need to determine the number of prey consumed in each time period.
In a week:
The owl produces two pellets every 24 hours. So, in one day, it consumes 2 * 3 = 6 prey (since each pellet contains the remains of 3 prey).
In a week (7 days), the owl consumes 6 * 7 = 42 prey.
In a month:
Assuming a month has 30 days (though some months have 31 days or 28/29 days), we can calculate the number of prey consumed in a month.
In a day: 6 prey
In a month (30 days): 6 * 30 = 180 prey.
Hence, the owl eats 42 prey in a week and 180 prey in a month.
